Problems solved by technology

However, the degree of overlap between the color filter pattern and the light-shielding layer will affect the surface flatness of the color filter pattern, thereby affecting the deflection of the backlight or ambient light passing through the color filter pattern
Once light passes through the color filter pattern and undergoes unexpected deflection, the optical quality of the color filter will be greatly affected

[0039] figure 1 It is a schematic partial top view of a color filter according to an embodiment of the present invention. Please refer to figure 1 , the color filter 200 of this embodiment includes a substrate 210, a light-shielding layer 220, a plurality of first color filter patterns 230 and a plurality of second color filter patterns 240, wherein the light-shielding layer 220, the first color filter The light pattern 230 and the second color filter pattern 240 are disposed on the substrate 210 , and the first and second color filter patterns 230 , 240 are arranged parallel to each other and alternately. Of course, the color filter 200 of this embodiment may further include other components, and figure 1 Omitting other components is mainly for the convenience of describing the following embodiments.

[0054] The spirit to be described in this embodiment is similar to that of the first embodiment, where the present embodiment also uses the three primary colors of light (red light, green light, and blue light) as an example to form a display screen. In the first embodiment, the color filter 200 is mainly designed based on the idea that the perception of green light by the human eye is higher than that of red light and blue light, so the red filter pattern and the blue filter pattern have substantially the same design parameters. Of course, in the application of actual products, color filters can be designed according to the difference in human perception of red light and blue light. Therefore, different design parameters are adopted for the red filter pattern and the blue and green light pattern in this embodiment, so as to further improve the optical quality of the color filter. However, if there are identical or similar symbols in the present embodiment and the previous em...

Abstract

The invention relates to a colored filter which comprises a base plate, a shading layer, a plurality of first colored filtering patterns and a plurality of second colored filtering patterns. The shading layer is provided with a plurality of openings that are arranged in array, wherein, the base plate is exposed through the openings. The first colored filtering patterns are parallel and staggered with the second colored filtering patterns. The first colored filtering patterns are positioned at a part of the openings and overlapped with the neighboring shading layer, and a first overlapping width is kept between the first colored filtering patterns and the shading layer. The second colored filtering patterns are positioned at the other part of the openings and overlapped with the neighboring shading layer, and a second overlapping width is kept between the second colored filtering patterns and the shading layer. The second overlapping width is not equal to the first overlapping width. The colored filter uses the colored filtering patterns with different colors and the size difference of the overlapping parts between the colored filtering patterns and the shading layer to improve the optical quality of the colored filterer, thus improving the optical quality of a display device.

Description

technical field [0001] The present invention relates to a filter structure, and in particular to a color filter. Background technique [0002] As far as a display device with a color filter is concerned, the color filter is mainly composed of a substrate and a light-shielding layer disposed thereon and a plurality of color filter patterns, wherein the color screen of the display device is illuminated by backlight or ambient light. Generated by color filter pattern. Generally speaking, the light-shielding layer can be used to shield the color mixing phenomenon between the color filter patterns of different colors, in other words, the light-shielding layer will be disposed between two adjacent color filter patterns. [0003] In practice, when forming a color filter, a light-shielding layer with a plurality of openings is first formed on the substrate, and then the color filter patterns are filled in the openings. However, in the actual manufacturing process, there are unavoi...
